In no long time thereafter he saw an armed warrior of hostile aspect coming towards him through the wood. No courteous greeting did he give to Dermot, but began to revile him for roaming in his wood and wilderness, and for drinking his water. Thereupon they fought, and for the rest of the afternoon they took and gave hard blows neither subduing the other, till at last as darkness began to fall the warrior suddenly dived into the well and was seen no more. Dermot, vexed at this ending of the combat, then made him ready to spend the night in that place, but first he slew a deer in the wood, and made a fire, whereat he roasted pieces of the deer's flesh on spits of white hazel, and drank abundantly of the well-water, and then slept soundly through the night.
Next morning when he awakened and went to the well he found the Champion of the Well standing there and awaiting him. "It is not enough, Dermot," said he angrily, "for thee to traverse my woods at will and to drink my water, but thou must even also slay my deer." Then they closed in combat again, and dealt each other blow for blow and wound for wound till evening parted them, and the champion dived into the well as before.
On the third day it went even so; but as evening came on Dermot, watching closely, rushed at the champion just as he was about to plunge into the well, and gripped him in his arms. But none the less the Champion of the Well made his dive, and took down Dermot with him. And a darkness and faintness came over Dermot, but when he awoke, he found himself in a wide, open country, flowery and fair, and before him the walls and towers of a royal city. Thither the champion, sorely wounded, was now borne off, while a crowd of his people came round Dermot, and beat and wounded him, leaving him on the ground for dead.
After night had fallen, when all the people of the city in the Land Undersea had departed, a stalwart champion, well-armed and of bold appearance, came upon Dermot and stirred him with his foot. Dermot thereon awoke from his swoon and, warrior-like, reached out his hand for his arms. But the champion said, "Wait awhile, my son, I have not come to do thee hurt or harm. Thou hast chosen an ill place to rest and slumber in, before the city of thine enemy. Rise and follow me, and I shall bestow thee far better than that." Dermot then rose and followed the champion, and long and far they journeyed until they came to a high-towered fortress, wherein were thrice fifty valiant men-at-arms and fair women; and the daughter of that champion, a white-toothed, rosy-cheeked, smooth-handed, and black-eyebrowed maid, received Dermot, kindly and welcomefully, and applied healing herbs to his wounds, and in no long time he was made as good a man as ever. And thus he remained, and was entertained most royally with the best of viands and of liquors. The first part of every night those in that Dún were wont to spend in feasting, and the second in recreation and entertainment of the mind, with music and with poetry and bardic tales, and the third part in sound and healthful slumber, till the sun in his fiery journey rose over the heavy-clodded earth on the morrow morn.
And the King of that country, who was the champion that had aroused Dermot, told him this was the land of Sorca, and that he had showed this kindness to Dermot for that he himself had once been on wage and service with Finn, son of Cumhal "and a better master," said he, "man never had."
Now the story turns to tell of what befell Finn and the remainder of his companions when Dermot left them in the ship. After a while, seeing that he did not return, and being assured that some mischief or hindrance must have befallen him, they made an attempt to climb the cliff after him, having noted which way he went. With much toil and peril they accomplished this, and then journeying forward and following on Dermot's track, they came at last to the well in the wild wood, and saw near by the remains of the deer, and the ashes of the fire that Dermot had kindled to cook it. But from this place they could discover no track of his going. While they were debating on what should next be done, they saw riding towards them a tall warrior on a dark grey horse with a golden bridle, who greeted them courteously. From him they enquired as to whether he had seen aught of their companion, Dermot, in the wilderness. "Follow me," said the warrior, "and you shall shortly have tidings of him."
Then they followed the strange horseman into the forest by many dark and winding ways, until at last they came into a rocky ravine, where they found the mouth of a great cavern opening into the hillside. Into this they went, and the way led them downward until it seemed as if they were going into the bowels of the earth, until at last the light began to shine round them, and they came out into a lovely land of flowery plains and green woods and singing streams. In no long time thereafter they came to a great royal Dún, where he who led them was hailed as king and lord, and here, to their joy, they found their comrade, Dermot of the Love Spot, who told them of all his adventures and heard from them of theirs. This ended, and when they had been entertained and refreshed, the lord of that place spoke to Finn and said:—
"I have now, O Finn, within my fortress the fifteen stoutest heroes that the world holds. To this end have I brought you here, that ye might make war with me upon mine enemy the Champion of the Well, who is king of the land bordering on mine, and who ceases not to persecute and to harry my people because, in his arrogance, he would have all the Under World country subject to himself alone. Say now if ye will embrace this enterprise and help me to defend my own: and if not I shall set you again upon the land of Erinn."
Finn said, "What of my fifteen men that were carried away on the wild mare's back oversea?" "They are guarding the marches of my kingdom," said the King of Sorca, "and all is well with them and shall be well."
Then Finn agreed to take service with the King of Sorca, and next day they arrayed themselves for fight and went out at the head of the host. Ere long they came upon the army of the King of the Well, and with him was the King of the Greeks and a band of fierce mercenaries, and also the daughter of the Greek King, by name Tasha of the White Side, a maiden who in beauty and grace surpassed all other women of the world, as the Shannon surpasses all rivers of Erinn and the eagle surpasses all birds of the air. Now the stories of Finn and his generosity and great deeds had reached her since she was a child, and she had set her love on him, though she had never seen his face till now.
